Okay, two new TSBs on the TT .. Here's the first one. I wish
I had a scanner that worked, because this thing is huge, but I'll try to give you a good summary:
*************************
C 01-02-07
Subject: Diagnosis of Driveability complaints on Turbo Charge Engines
Date: September 30, 2002
Model(s): TT, S4, A6, Turbo (Drive by wire) A4 with 1.8T (Drive by Wire) 2000 > 2003
Condition: Mass Air Flow (MAF) sensor incorrectly replaced due to rough idling, vehicle hesitation, car lacks power, multiple misfires or the following DTCs stored in DTC memory:
P0103, P1111, P1112, P1128, P1130, P1144, P1145, P11476, P1147, P1148 or P1557
All of the listed DTCs except P1144, P1145 and P1146 may be caused by air leaks in the pressure side of the air duct.
Service:
Before replacing the MAF sensor, on turbocharged vehicles with Electronic Throttle Control (Drive by Wire), check the following according to DTC:
P1144 (Mass or Volume Air Flow Circ. open/short to Ground), P1145 (Mass or Volume Air Flow Circ. open/short to B+), P1146 (Mass or Volume Air Flow Circ. Power malfunction: Check Electrical Connections of MAF sensor and harness.
P0103 (Mass or Volume Air Flow Circ. High Input) and P1557 (charge Pressure Contr. Positive Deviation): Check for Air Leaks in Pressure Side Air Duct.
P1111 (O2 Control - Bank 1 - System too lean) and P1147 (O2 Control - Bank 2 - BiTurbo only - System too lean): Check Air Duct for Air Leaks between MAF sensor and turbo charger inlet and downstream throttle (intake manifold).
P1112 (O2 Control - Bank 1 - System too rich) and P1148 (O2 Control - Bank 2 - BiTurbo only - system too rich): Check for Air Leaks in Pressure Side Air Duct
P1128 (Long Term Fuel Trim mult. - Bankk 1 - system too lean) and P1130 (Long germ fuel trim mult. - Bank 2 - BiTurbo only - Sytem too lean): Check Air Duct for Air Leaks between MAF and turbo charger inlet and downstream throttle (intake manifold)>
__________
It then goes on for about five pages on how to do this and then says:
If no leaks are found in the pressure side air duct and additional checks have been performed and NO cause found and if the following DTCs still exist: P0102, P1111, P1147, P1112, P1148, P1128, P1130: Replace MAF sensor.

So, without a scanner, you are transcribing these? Wow. Thanks.
Scanners are now incredibly cheap, like $65 for a nice HP low end (but amazing performance) scanner.
How much is the subscription again? Maybe I should subscribe and scan these things for the TT community.

I've got one that I can't get to work...keep meaning to go get a new one...the subscription
is only $40 and doesn't look like you need to renew it. Caution: if you subscribe, look for a monthly plain brown envelope that looks like junk mail. Have come close to throwing them out without opening a few times.
